How to retrieve the Relative Record Number? - response (10) by wicik

Well...
 
Sounds stupid but I have helped myself with default select --> copy paste to excel --> sorting and numeric conversion to date via left and right functions (to split needed numbers and connecting it as a date) and by makeing a PivotChart from all of it.
 
It gave me pretty the same but not that pro as it should.
Still, any help would be welcome :)
I need to learn how to do it properly.
 
Regards
